Duty Cycle Calculator

Enter the pulse width and the period into the calculator to determine the duty cycle.

Duty Cycle Formula

The following formula is used to calculate a duty cycle.

D = PW / T

  • Where D is the duty cycle
  • PW is the pulse width (s)
  • T is the period (s)

FAQ

What is a duty cycle?

A duty cycle measure the amount of time a transmitter is emitting a signal. This time is often a fraction of a total frequency period. The longer the duty cycle, the stronger the transmittion.


Duty Cyle Example

How to calculate duty cycle?

  1. First, determine the pulse width.

    For this example we will say the pulse width is .03 seconds.

  2. Next, determine the period.

    For this example we will assume the period is .05 seconds.

  3. Finally, calculate the duty cycle.

    Using the formula above we find the duty cycle is: .03/.05 = .60 = 60%.
